A new world of detail and precision

Hear details you’d never noticed before. Feel like you’re right in the middle of the action. That’s what the HD 550 sound gives you in a light, comfy, accessible package.

Lots of mainstream audio products give you “bathtub” sound. They call it that because the frequency response curve is shaped like a bathtub. We like a nice soak as much as the next person, but with bathtub sound you’re drowning in bass and treble, vocals are weak, and certain frequencies resonate too loudly.

So light and comfortable they practically disappear

Has there been a contest for “most performance per gram”? If so, the HD 550 probably won. At just 237 g, they’re about as unobtrusive as possible.

The HD 550 design is heavily influenced by feedback from people like you. And you said, “make it light, make it comfy, and make it sound great.” So we revised the headband, using high-quality synthetic leather and softer foam.
